The stars of “The Big Bang Theory” are about to have one million reasons to be thankful for their hit CBS show.

Jim Parsons, Johnny Galecki and Kaley Cuoco are close to signing new deals worth around $1 million an episode, according to deadline.com.

The three-year pacts (good through the already renewed 10th season) would see the trio of cast members triple their salaries from the $350,000 an episode they were earning under their most recent contracts.

In a nod to the huge success of the show — “The Big Bang Theory” is the most-watched show on television, averaging 23 million viewers last season — the new deals also reportedly include an increased share of the back-end profits (syndication sales, etc.) and development deals for the actors.
